A. Amazon S3
B. Amazon Glacier
C. Amazon Elastic Block Store (Amazon EBS)
D. Amazon Elastic File System (Amazon EFS)

Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed elastic NFS file system for use with AWS Cloud services and on-premises resources. It is built to scale on demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files, eliminating the need to provision and manage capacity to accommodate growth.
Amazon EFS is designed to provide the throughput, IOPS, and low latency needed for Linux workloads. Throughput and IOPS scale as a file system grows and can burst to higher throughput levels for short periods of time to support the unpredictable performance needs of file workloads. For the most demanding workloads, Amazon EFS can support performance over 10 GB/sec and up to 500,000 IOPS.

Explanation:
Cloud services main proposition is to provide elasticity through horizontal scaling. Itג€™s already there. As for using largest instance possible, it is not a design principle that helps cloud applications in anyway. Scrum development process is not related to architecting. Therefore, a key principle is to provision your application for on-demand capacity. Peak loads is something that cloud applications experience everyday. Peak load management should be a necessary part of cloud application design principle.

Question 80 ( Topic 1 )
If a customer needs to audit the change management of AWS resources, which of the following AWS services should the customer use?
A. AWS Config
B. AWS Trusted Advisor
C. Amazon CloudWatch
D. Amazon Inspector

Answer : A

Explanation:
AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. Config continuously monitors and records your
AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations. With Config, you can review changes in configurations and relationships between AWS resources, dive into detailed resource configuration histories, and determine your overall compliance against the configurations specified in your internal guidelines. This enables you to simplify compliance auditing, security analysis, change management, and operational troubleshooting.

Question 82 ( Topic 1 )
Which service allows a company with multiple AWS accounts to combine its usage to obtain volume discounts?
A. AWS Server Migration Service
B. AWS Organizations
C. AWS Budgets
D. AWS Trusted Advisor

Answer : B

Explanation:
use the consolidated billing feature in AWS Organizations to consolidate billing and payment for multiple AWS accounts or multiple Amazon Internet Services Pvt.

Question 85 ( Topic 1 )
Which design principles for cloud architecture are recommended when re-architecting a large monolithic application? (Choose two.)
A. Use manual monitoring.
B. Use fixed servers.
C. Implement loose coupling.
D. Rely on individual components.
E. Design for scalability.

Answer : CE

Explanation:
Rearchitecting applications involves sweeping change where an old monolithic application is completely revamped according to modern microservices architecture. Using individual components to re-architect a big application is one part of the process. The most important part is to design the application for scalability because the level of investment for a monolithic application can only be justified when resilience and scalability is needed.

A. Amazon Elastic Block Store (Amazon EBS)
B. Amazon Machine Image
C. Amazon EC2 Systems Manager
D. Amazon AppStream 2.0

✑ Configure security and network access on your Amazon EC2 instance.
✑ Choose which instance type(s) you want, then start, terminate, and monitor as many instances of your AMI as needed, using the web service APIs or the variety of management tools provided.
✑ Determine whether you want to run in multiple locations, utilize static IP endpoints, or attach persistent block storage to your instances.
✑ Pay only for the resources that you actually consume, like instance-hours or data transfer.

Question 92 ( Topic 1 )
How would an AWS customer easily apply common access controls to a large set of users?
A. Apply an IAM policy to an IAM group.
B. Apply an IAM policy to an IAM role.
C. Apply the same IAM policy to all IAM users with access to the same workload.
D. Apply an IAM policy to an Amazon Cognito user pool.

Answer : A

Explanation:
Instead of defining permissions for individual IAM users, it's usually more convenient to create groups that relate to job functions (administrators, developers, accounting, etc.). Next, define the relevant permissions for each group. Finally, assign IAM users to those groups. All the users in an IAM group inherit the permissions assigned to the group. That way, you can make changes for everyone in a group in just one place. As people move around in your company, you can simply change what IAM group their IAM user belongs to.

Question 93 ( Topic 1 )
What technology enables compute capacity to adjust as loads change?
A. Load balancing
B. Automatic failover
C. Round robin
D. Auto Scaling

Answer : D

Explanation:
AWS Auto Scaling monitors your applications and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost. Using
AWS Auto Scaling, itג€™s easy to setup application scaling for multiple resources across multiple services in minutes. The service provides a simple, powerful user interface that lets you build scaling plans for resources including Amazon EC2 instances and Spot Fleets, Amazon ECS tasks, Amazon DynamoDB tables and indexes, and Amazon Aurora Replicas. AWS Auto Scaling makes scaling simple with recommendations that allow you to optimize performance, costs, or balance between them. If youג€™re already using Amazon EC2 Auto Scaling to dynamically scale your Amazon EC2 instances, you can now combine it with AWS Auto
Scaling to scale additional resources for other AWS services. With AWS Auto Scaling, your applications always have the right resources at the right time.

Question 102 ( Topic 1 )
Which of the following is an AWS Cloud architecture design principle?
A. Implement single points of failure.
B. Implement loose coupling.
C. Implement monolithic design.
D. Implement vertical scaling.

Answer : B

Explanation:
Loose coupling between services can also be done through asynchronous integration. It involves one component that generates events and another that consumes them. The two components do not integrate through direct point-to-point interaction, but usually through an intermediate durable storage layer. This approach decouples the two components and introduces additional resiliency. So, for example, if a process that is reading messages from the queue fails, messages can still be added to the queue to be processed when the system recovers.

Question 103 ( Topic 1 )
Which of the following security measures protect access to an AWS account? (Choose two.)
A. Enable AWS CloudTrail.
B. Grant least privilege access to IAM users.
C. Create one IAM user and share with many developers and users.
D. Enable Amazon CloudFront.
E. Activate multi-factor authentication (MFA) for privileged users.

Answer : BE

Explanation:
If you decided to create service accounts (that is, accounts used for programmatic access by applications running outside of the AWS environment) and generate access keys for them, you should create a dedicated service account for each use case. This will allow you to restrict the associated policy to only the permissions needed for the particular use case, limiting the blast radius if the credentials are compromised. For example, if a monitoring tool and a release management tool both require access to your AWS environment, create two separate service accounts with two separate policies that define the minimum set of permissions for each tool.
